. v Adppllieaitimm ll/fay 2, i935, Serial No. lllbd v e claims. (ci. eea-rre) This invention relates to av combined latch and lock structure designed primarily for use in connection with doors of automobiles, but it is to be understood that it is adapted for use in any connection in which it may be found applicable.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a combined latch and lock structure which is durablethor oughly emcicnt in its use,,conveniently'operated to released position from. the outside and inside of a door, readily installed, permanently tending to latch the door and inexpensive to manufacture.

With the foregoing and other objects in view, the inventioniconsists of such parts and combination of parts as are hereinafter more specically described and as are illustrated in the accompanying drawing,'wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fallwithin the scope of the invention as claimed.

In the drawing:

Figure 1 is a fragmentary view of a door and door frame of an automobile showing the adaptation therewith of the combined latch andl lock structure,

Figure 2 is a fragmentary view in vertical section of thedoor and door frame of an automobile showing the adaptation therewith of the combined latch and lock structure, and

Figure 3 is a view similar to Figure 2 of a modied form.

The drawing illustrates at t oneof thesides of a door frame formed with a triangularfshapcd socket or keeper l... Theside 6 has a metallic facing il which conforms in contour to that of the side. A side bar 9 of a door I0 is also shown. 'The bar 9 is formed of upper and lower superimposed sections 9e, 9b which constitute a supporting means. for a latching member and releasing plunger to be hereinafter referred to. The bar 9 is provided with a pair of oppositely disposed concavities Il,i2 in its front and inner faces i3, respectively and a circular channel l which extends from the base of concavity ll to the base of concavity I2.' The channel opens .into and axially of the bases of the concavities. The door I0 is provided with a metallic facing IB formed with a. pair of circular openings ll, i8 havingxtheir edges registering. with the walls vof the concavities Il, I2 respectively. is also formed with a rectangular opening i9. Otherwise than that as stated, the facing I6 conforms in contour to that of the door body. The

bar 9 is provided with a rectangular, horizontally disposed passage 2U which opens at the outer and inner side edges 2l, 22`respectively thereof and is intersected centrally by the channel -|5. The outer end of passage 20 registers with the openi lng i9. The passagev 2:0 is formed in the upper The facing end of section fb of bar d andhas its top wall provided by the bottom of section d of bar t. The channel it is formed in the sections da, d of bar t at the meeting ends of the said sections. Extending into the concat/ities i l, if is a pair of oppositely disposed flanged. metallic cup-shaped members ff, fil respectively having axial openings fb, ft respectively registering with theends i The member fl is of rectangular contour in cross section and consists of a bar db having a beveled outer end llt, a transverse groove fl in its upperfface to provide a 'clearance 4for a purpose to be referred to. The forward wall ft of groove 3l is square. Tlfie rear wall lid ofgroove dll is inclined rearwardly in opposite outward -directions. At the center ofwall 39 it is undercut to form a recess til. Journaled in bar 35 and arranged within nd extending from recess 4B is a vertically disp ed bearing roller di. The rear end of bart is rabbeted, as at 42'. 'The member 2d includes a shank 43 of square cross section which is integral withand extends rearwardly. from the vertical edge and is spaced above and projects beyond the rear end of the horizontal edge provided by the rabbet d2. is slldably mounted in and is of greater length than that' of passage 2li. The controlling spring 32, to Abei hereinafter more fully referred to, permanently tends to maintain thebeveled end of-member 29 in the socket l to latch the door and bar 35 against plunger fltl to prevent rattling. The walls of socket lare lined with the facing iB. The releasing plunger 30 is slidably mounted in channel l5. and consists of a transverselydis- The member fd The flanges of the members ft,

beveled. The body 44 is out out to form a vertically disposed. triangular shaped notch 4l and transverse median of said body 44 at a point betweennthe longitudinal median and the other side oi' body 44. The width of the major portion oi the notch Il is greater than the width oi member to. The lower face of body 44 is provided with a transverse groove Ell oi greater width than the portion oi greatest width ci notch el. The groove tu provides for the seating of body Ul on member 2S in the groove 3l. The latter, notch 4l and groove dil provide clearances for the member 29 and plunger 30 relative to each other on their shifting. The body M is formed lengthwise and concentrically thereof with a circular soclret iii which opens at the end` db thereoi?. The body dit is also formed with a diametrically extending passage E52 which opens into socket Si and at the said other side of the periphery of body lili. `The working faces titi, when the plunger is slid inwardly and outwardly respectively, act on the roller di to shift the latching member to released position against the action oi controlling spring The locking element 3i is of any well lmown type of cylinder lool; which is secured in and slightly extended from the outer end of socket di. The locking ooit of element Eli is mounted in passage "si and when actuated to loching posiu tion, extends into a socket formed in bar to prevent a sliding action being had on plunger to release the member from its latching position. until the loclring bolt of element 3i is shifted to unlocking position. k

rlhe controlling spring di is mounted on shank dit between the vertical edge oi rabbet and the combined guide and tensioning means The latter consists of an angle-shaped member iormed of a vertical and a `horizcncltal leg 55 respectively. I'l'he leg 5t has a large square opening t6 through which extends the shanlr d3. The leg di ls of greaterY length than and depends from the forward end oi leg dii. The leg lit is capable oi being adjustable forwardly and rearwardly of the shank 45t for increasing and decreasing the tension of spring 32. The means is held in its adjusted position by a detachable holdfast device l' carried by leg d5 and selectively engaging in one of the openings of ther 'set o spaced openings 58 yformed in the hanger 34. The latter, at its forward end, has an upstanding flange 59 which is anchored against the inner edge of bar 9 by the holdfast means 5o.

The i'orm of the invention shown in Figure 3 is the same as that shown in Figures l and 2 with the exception that the shank 'li of the latching member l2 shown in Figure 3 is of greater length than the shank of the latching member 29. A holder 13 has the rear end of shank 'H arranged therein. The top edge of shank ll contacts with the lower end of a fixed bearing member 74. The holder 13 and member 14 are anchored to door body lo.

'Otherwlsethan that as stated, the modifledform will be the same as the form of the invention shown in Figures l and 2. l

When assembling'thestructure, the elements 33 'and 3l are secured together and with element 33 depending from element 34.

whereby the latter Will extend into the groove of the plunger. When the plunger is mounted relative to member 29 it extends into the lower portion of the channel l5. The section 9 of bar 9 is then mounted on the top of section 9b in a. manner to have the plunger 30 arranged in the upper portion of channel i E. The sections 9, 9b oi bar 3 are then secured together and the element i3 is then positioned on the rear of shank 43 against spring 32. The element 34 is then secured to the section t of the bar 9.

vWhen using the latch and loch structure for house doors, the latching member, would be made oi round stock instead of rectangular or square stoel; to enable the structure to be installed without making a mortise in the door.

What i claim is:
